    摘要: A method for manufacturing a fluid bearing is provided. A mask member having at least two sets of grooves provided at least two places along an axial direction is affixed to an outer surface of an electrode section of a fluid bearing manufacturing tool. Each of the groove sets consists of multiple grooves in a shape corresponding to designed fluid bearing grooves on a work piece, such as, for example, a sleeve section of the fluid bearing. The fluid bearing manufacturing tool is inserted into a hole created in the work piece, wherein a power source for electrolytic machining is connected between the fluid bearing manufacturing tool and the work piece. An electrolytic solution between the manufacturing tool and the work piece is allowed to flow to form fluid bearing grooves on an inner surface of the work piece through electrolytic machining.

    摘要: To accurately locate a fluid dynamic bearing element along a shaft, the shaft is excited at or near its resonant frequency while applying a press force to the shaft, and holding the bearing element still. The assembly process then becomes a dynamic process, with the result that the positioning or locating of the shaft relative to the cone or other bearing element can be achieved with much greater accuracy. A PZT (piezoelectric) element may be located between the press and the motor shaft with the frequency of the PZT element being a function chosen to effectively oscillate the shaft at or near its resonant frequency; thus the PZT element should be excited at the approximate axial resonant frequency of the shaft. The press structure which is used to apply the press force should have sufficient stiffness so as not to absorb the energy created by the PZT element, which would damp its effects.

    摘要: The specification discloses a device and method for manufacturing fluid bearings. The invention utilizes the electromagnetic forming method to manufacturing fluid bearings. The method uses a high speed plastic forming means to produce a dynamic pressure generating groove on the internal peripheral surface of the bearing. It further makes use of different thermal expansion coefficients for an internal mold and a raw sleeve to perform separation from the mold. Through the above-mentioned process, fluid bearings can be successfully made. This method can effectively prevent the problem springback and crease of the material during formation.

    摘要: There are provided a spherical bearing and a method for manufacturing the same, in which both of a ball bearing section and a ball section made of metal can make light and smooth swinging and rotary motions for a long period of time without biased wear and seize-up of those members even if the solid bodies of them can contact with each other due to a discontinuous oil film under a heavy load. A resin liner that contacts the ball section of the inner member in a sliding relationship is embedded in the ball bearing section, and a resin sliding contact surface provided by the resin liner and the metal sliding surface are adjacent to each other without any gap to form a sliding contact surface at the bearing section.

    摘要: A method of assembling a motor comprising assembling the shaft and thrust plate to be used in the fluid dynamic bearing assembly, and at least partially inserting the combined shaft and thrust plate into a sleeve which is adapted to support a hub which in turn may support one or more disks for rotation in a disc drive or similar environment. A counterplate cup of a generally U shaped or cup shaped design including a base which is substantially parallel to a top surface of the thrust plate, and sides of a diameter which is slightly greater than the diameter of the thrust plate and which are parallel to the thrust plate is provided, filled with oil, and having its open end facing the thrust plate. Next the shaft and hub are pressed with the counterplate cup, the counterplate cup being pressed down over the end of the thrust plate so that the upraised sides of the cup fit easily over the ends of the thrust plate and can be pressed fit tightly over the upraised outer surface of the sleeve, tightly fitting the inside of the counterplate cup over the outside surface of the sleeve. During this press fit, the oil is pushed out of the region between the thrust plate upper surface and the counterplate cup bottom surface, and as the upraised sides of the cup fit over the outside of the sleeve, the oil fills the section between the lower surface of the thrust plate and the upper surface of the sleeve as well as the gap between the shaft and the surrounding sleeve.

    摘要: A rolling guide apparatus comprises a first slide member and second slide member. The first slide member includes a pair of wing portions and a connecting portion connecting the wing portions. First raceway grooves are formed on the wing portions, individually. Second raceway grooves are formed on the second slide member. Rolling elements are held under a pre-load between the raceway grooves. A residual compression stress region is created on the surface region of the first slide member. A worked portion is formed on the connecting portion. The worked portion serves to adjust the pre-load on the rolling elements by regulating the residual compression stress region by working to deform the connecting portion.
